    A alone can complete a work in 18 days and B alone in 15 days. B alone worked at it for 10 days and then left the work. In how many more days, will A alone complete the remaining work?

    A)  5                   

    B)  \[5\frac{1}{2}\]

    C)  6                   

    D)       8

    Correct Answer: C

    Solution :

     Part of work done by Bin 10 days \[=10\times \frac{1}{15}=\frac{2}{3}\] Remaining work \[=1-\frac{2}{3}=\frac{1}{3}\] \[\therefore \]  Time taken by \[A=\frac{1}{3}\times 18=6\] days
